APPARATUS FOR ROLLING BEAMS.

SPECIFICATION formingpart of Letters Patent No. 520,060, dated May 22,189

Application filed April 24, 1893.

T0 at whom it may concern:

Be it known that I, FREDERICK H. KINDL, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Apparatus for Rolling Beams, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a plan view of rolls and feedtables; and Fig. 2 is avertical sectional View on the line 11-11 of Fig. 1.

Like symbols of reference indicate like parts in each of the views.

In the drawings, the letters a to m represent the vertical rolls whichare journaled in the housings 8 and 4 and are connected with the drivingspindles 5 by the wabblers 6. Keyed to the lower end of the spindles 5are the bevel-wheels 7, which gear with bevel- Wheels8 on the shaft 9,so that each roll is driven by power directly from the powershaft. Inthe face of the rolls 2 are grooves 10, which form the flanges of thebeam, and these grooves, as well as the space between the rolls,diminish in size with eachpass of the series from a to m, so as toreduce the thickness of both the flanges and the web of the beam witheach pass. On each side of the rolls 2 are the feed-tables a to 10',having feed-rollers 11, which are driven by suitable mechanism in thedirection of the arrows marked on the drawings. The rolls a to m are soconstructed that they may be adjusted in relation to each other bysuitable mechanism, not shown in the drawings, so as to increase ordiminish the space between the rolls on any or all of the differentpasses.

The operation is as follows:-The I-beams or channel-beams as they comefrom the cogging mill are delivered with their webs in a verticalposition to the feed-table a, and are passed between the rolls a b tothe feed-table b. By suitable transfer mechanism, not

shown in the drawings, the shape is then transferred to the feed-table cand passed between the rolls 6 and c, and so on until the finished beamis delivered on the table w.

The advantages of my invention will be Serial No. 471,570. (No model.)

are much cheaper, being smaller in length, than the horizontal rolls nowin general use and hence are easier to replace in case of breakage orchange from one shape to a1 1- other; as one roll is used in two passesa minimum number of rolls is required. They are also much stronger owingto the short distance between their bearings, and, being on the samelevel, can be easier adjusted than 1f arranged three-high, as now mostlyused. As the rolling is all done on one and the same horizontal planeand the feed-rollers turn in the proper direction, the use of tilting aswell as transfer tables is avoided, and a continuous rolling of theshape is accomplished, making it less expensive to roll and increasingthe output or tonnage over that of the present method. Each roll is alsodriven lndependently by power derived directly from the power shaft;thus the strains in the connections, wabblers, and rolls are greatlyreduced from those existing in the present mills, hence causing lessbreakage.

Although I have shown rolls adapted to roll I-beams, I do not desire tolimit myself ftheretcgrnondolllesire fol i mihmynlnvenflorl to the useof the particular devices shown and described; it being understood thatfor channel beams which are not symmetrical about their vertical axis,suitable means must be provided for turning this shape, so as to set itin proper position for entering the consecu tive passes.

I am aware that vertical rolls used singly or in'connection withhorizontal rolls are not new.

I am also aware that vertical rolls have been used in rolling tubes, andI do not desire to claim the same broadly.

Having thus described my invention, what I claim, and desire to secureby Letters Patent is.-

1i In a rolling mill plant, the combination of a series of three or morevertical rolls, having grooves adapted to roll channel-beams, the grooveof the intermediate rolls being adapted to coact with the grooves on therolls on each side of it, the faces of the rolls being arranged at asuccessively less distance apart;

apparent to those skilled in the art. The rolls substantially asdescribed.

2. In a rolling-mill plant, the combination of a series of three or morevertical rolls, havmg grooves adapted to reduce channeled beams fromtheir first shape to the finished 5 beam, and a series of horizontalfeeding tables having feed rollers arranged to feed the beams throughthe passes of the rolls; substantially as described.

3. The combination of a series of vertical rolls, and a series offeed-tables, all of which IO tables are situate in the same horizontalplane; substantially as described.

In testimony whereof I have hereunto set my hand.
